So I'll answer my own question in case anyone else is trying to render html
emal with Tap 4.1
The underlying problem was not swapping out the DefaultResponseBuilder from
RequestGlobals and also having to implement ResponseBuilder.
Here is a snippet of code.
ResponseBuilder defaultBuilder =
getRequestGlobals(cycle).getResponseBuilder();
IEngine engine = cycle.getEngine();
RequestCycleFactory factory = getRequestCycleFactory(cycle);
IRequestCycle inner = factory.newRequestCycle(engine);
String[] subjectAndBody = new String[2];
BaseHTMLMessagePage sendPage = (BaseHTMLMessagePage)
getHtmlPage(inner);
ByteArrayOutputStream out = new ByteArrayOutputStream();
IMarkupWriter writer = new MarkupWriterImpl("text/html", new
PrintWriter(out), new AsciiMarkupFilter());
ResponseBuilder builder = new EmailResponseBuilder(writer,
engine.getInfrastructure().getAssetFactory(), false, cycle);
getRequestGlobals(cycle).store(builder);
inner.activate(sendPage);
inner.renderPage(builder);
writer.flush();
subjectAndBody[0] = sendPage.getSubject();
subjectAndBody[1] = out.toString();
inner.cleanup();
Notice the storing of the EmailResponseBuilder in requestGlobals and then
replacing it with the original DefaultResponseBuilder.
I'm not sure if all of this was necessary but it's the only way I could get
it to work. I will investigate using hivemind to wire up the
EmailResponseBuilder and also the HtmlEmailPage. But for now this is how I
got it to work.

I don't know 4.1, but if you provide a Response and replace the
outputstream, you'll likely get what you want. You'll just have to
ensure the headers don't get sent, but I believe that is a method you
can overload in the Response.
